How it held up in sell-offs (GLD)

PeriodStrategyBuy & hold
Q4 2018 sell-off+2.5%+6.6%
COVID crash (Feb–Mar 2020)-3.6%-3.6%

Market below its 200-day average (annualized) · 42%+3.8%+5.4%

Sell-off dates follow the US stock market. Above/below the 200-day average uses the previous day's position, so there is no look-ahead.

Out-of-sample check (GLD)

Chosen parameters on their 3-year training windows (average Sharpe)0.63
Same parameters in the following 6 months, when traded (Sharpe)0.35

Sharpe across settings: worst / median / best0.18 / 0.31 / 0.45

Out-of-sample periods start on 2013-01-04. Training-window figures are flattered by picking the best of 9 settings; the out-of-sample figure is what the strategy actually earned. A large drop, or a result that depends on one setting, points to overfitting. How walk-forward testing works.
